I'm fitting new pipes to my chassis, and the new metric unions don't fit the limiter valve and master cylinder. Advice sought on obtaining the right parts?
Brake pipe unions were a bit of a mix and match. On my GTLs the front brakes have been metric and the rear brakes imperial. Most of my master cylinders have been metric.
All the 60/70s and some 80s with Bendix brakes should be imperial threads because they were English Lockheed/Girling systems. Automec in Bedfordshire can supply you with allthe parts in copper or as Malclom says any good motor factors should have them.
